Package: octave2.9
Version: 1:2.9.14-1
Severity: normal

octave> s=struct("a",{},"b",{},"c",{},"d",{});
octave> s(1).a=1;
octave> [s(1).b s(1).c s(1).d]=sscanf("2 3 4","%d %d %d","C");
octave> s(2).a=11;
octave> [s(2).b s(2).c s(2).d]=sscanf("12 13 14","%d %d %d","C");
error: some elements undefined in return list
error: evaluating assignment expression near line 42, column 25

This error does not happen with octave 2.1.73-13, which indeed does the
expected thing.

Octave 2.9.14-1 does something different, which in my opinion is an
error, and which is not easy for me to explain in words.  Just remove
the semicolons at the end of the statements and see for yourself.
